Volvo 850 – Upgrade cruise control?

Hey municipality, In the logbook of my future Volvo I saw that some models have the turn signal lever equipped with cruise control. I get a V10 with 144hp, but without a computer on board. Only the displays for outside temperature and time can be seen. Now I know from some other brands and models that the cruise control could be retrofitted by simply replacing the turn signal stick (example: Vectra B 2.2 TDI) Is this also possible with the Volvo? has anyone ever done this before? Questions about questions…
